mkimage.sh loops forever

pietrushnic

I'm trying to follow this tutorial and it looks like mkimage.sh loops forever (I stopped watch when processing system.img reached 9.5GB interestingly du show about 470MB).

[16:22:51] pietrushnic:firefly-rk3288 gitmaster*) $ ./mkimage.sh
TARGET_PRODUCT=rk3288
TARGET_HARDWARE=rk30board
system filesysystem is ext4
create boot.img without kernel... done.
create recovery.img with kernel and with out resource... done.
create misc.img.... done.
create system.img...

I'm using e2f2ba5dd349 tag: Firefly-RK3288_Android4.4_201504181055. I wonder what is the purpose of loop in mkimage.sh:

                  while [ "$ok" = "0" ]; do
                          make_ext4fs -l $system_size $MAKE_EXT4FS_ARGS >/dev/null 2>&1 &&
                          tune2fs -c -1 -i 0 $IMAGE_PATH/system.img >/dev/null 2>&1 &&
                          ok=1 || system_size=$(($system_size + 5242880))
                  done  

Looks like I'm looping here forever. My system.img from ./out/target/product/rk3288/system.img file size is 399306712.

Any idea how to pass mkimage.sh script ?

Probably your "losetup" device is busy...
Try restarting your machine an see if it can create the image...
It needs to add a loop back device and mount to copy the system image.
Sometimes the loop back device is occupied and it cannot create other loop back device.
Restart and test...

You can get a list of loop back devices currently in use by command  "losetup -a"

Thanks for reply.

Ok the key information was that it should create loop device. it need root privileges to to do that.

1. sudo ./mkimage.sh

Copy the code

Did the trick. Thanks for helping out.

BTW to check loop devices

1. losetup -a

Copy the code

should be used at least for Debian.
